Trapped House Escape Game

You were walking on the street when you glanced up and saw a woman in the window of a flat on the Baker Street. She was about to jump out. You shouted at her to wait and stop it. You rushed into the house up to her door. Luckily, it was open so you barged in. The window was already closed and the women was nowhere to find. Maybe you missed the door? No, this is the window for sure. Then what happened? Did she hide somewhere? Or ran away? Wait... The door locked itself behind you. Great, now what? You still have to find her too. Let's find the spare keys!
